The difference between the numbers 037 and 192 is 155. This difference is always the same on all checked numbers.

Motorcode PYN

Engine Code PYN

The engine code number PYN is located above the engine serial number (forward LH side of engine). The engine serial number was the same as the chassis number when the car was delivered new from factory (matching numbers).
